Best Smart Toilets: 4 Bidet Seats & Toilets Compared

Smart toilets and bidet seats can add warm-water cleansing, heated seating, drying, and hands-free features, but fit and installation matter as much as comfort. For a complete fixture, the Kohler Innate is our top verified pick because it combines integrated cleansing, dual-flush operation, automation, and a 12-inch rough-in. The Woodbridge B0960S is the value pick for broad smart-toilet features at a lower price tier.

We checked current manufacturer specifications, linked Amazon listings, fit requirements, electrical needs, product status, and safety information. No hands-on testing is claimed.

Smart Toilets and Bidet Seats: Our Top Picks

Smart Toilet and Bidet Seat Reviews

Bottom line: The Kohler Innate is the strongest verified choice here if you want a complete smart toilet rather than a retrofit seat. It combines personal cleansing, automated lid and flush functions, heated comfort, drying, and a dual-flush design.

• Format: One-piece elongated smart toilet, integrated fixture and bidet.
• Cleansing: Front/rear warm-water wash, with adjustable spray settings.
• Comfort: Heated seat and warm-air dryer, built into fixture.
• Installation: 12-inch rough-in and dedicated GFCI circuit required.

The stainless-steel cleansing wand supports adjustable position, pressure, temperature, spray shape, pulsating, and oscillating functions. Kohler also specifies UV-light wand cleaning, a pre-use bowl mist, automatic deodorization, a nightlight, and motion-activated cover operation.

The skirted one-piece body reduces exposed exterior contours, while ReadyLock is designed to simplify installation on a standard 12-inch rough-in. This is still a full fixture replacement, so confirm the water-supply position and electrical location before ordering.

The electrical requirement deserves special attention. Kohler specifies one dedicated 120 V, 15 A, 60 Hz circuit protected by a Class A GFCI for this model.

Ease Of Use

Maintenance

Use cleaners allowed by Kohler, follow the specified wand-cleaning procedure, and keep the water shutoff and electrical connection accessible. If an electronic, motorized, or flushing function becomes unreliable, follow the service guidance instead of forcing the mechanism.

Bottom line: The Woodbridge B0960S is the better value choice if you still want a complete smart toilet. It combines hands-free lid operation, automatic flushing, bidet cleansing, heating, drying, and remote control.

• Format: One-piece elongated smart toilet, complete fixture replacement.
• Cleansing: Posterior and front wash, with adjustable water pressure.
• Comfort: Heated seat and warm-air dryer, plus deodorization.
• Installation: Standard 12-inch rough-in and 110–120 V power.

The B0960S uses a chair-height elongated design with a seat height listed by Woodbridge at 17-1/8 inches. That can reduce how far many adults need to lower themselves compared with a shorter conventional bowl.

Automatic lid opening and closing, automatic flushing, a wireless remote, and a nightlight reduce the number of manual steps during normal use. The wash system also provides adjustable pressure and filtered water.

This model uses a single-flush configuration rather than the Kohler’s dual-flush approach. Confirm the fixture dimensions, rough-in, supply placement, delivery access, and nearby electrical connection before installation.

Ease Of Use

Maintenance

Use cleaners permitted by Woodbridge, operate the nozzle-cleaning functions as directed, and keep the water and electrical connections accessible. Check connections after installation and follow the manual for filter, remote-battery, or service procedures.

Bottom line: American Standard marks model 8017A60GRC-291 as discontinued. Treat it as a legacy replacement component for an appropriate Advanced Clean 100 SpaLet installation rather than a current universal bidet-seat recommendation.

• Format: Electric bidet seat unit, not a complete toilet.
• Cleansing: Separate front and rear self-cleaning nozzles.
• Comfort: Instant warm water, heated seat and warm-air dryer.
• Installation: Fit-specific SpaLet hardware and AC power required.

The verified feature set includes independent front and back cleansing sprays, nozzle cleaning before and after use, instant warm water, five heated-seat settings, a nightlight, warm-air drying, and automatic seat opening and closing.

The more important buying issue is fit. This older seat belongs to American Standard’s Advanced Clean 100 SpaLet system, and the manufacturer now lists the exact 8017A60GRC-291 unit as discontinued. Do not assume it will fit a conventional elongated toilet just because the bowl shape looks similar.

Ease Of Use

Maintenance

Use only cleaners allowed for the seat and nozzle, keep the water and electrical connections accessible, and follow the original service documentation for replacement parts. Because the model is discontinued, confirm parts and service support before relying on it as a replacement.

Bottom line: The Duravit SensoWash Starck is now a legacy, fit-specific shower-toilet seat. Duravit identifies SensoWash Classic as its successor, so this older Starck unit makes the most sense only when you are matching a compatible existing Duravit installation.

• Format: Electric shower-toilet seat, designed for selected Duravit bowls.
• Cleansing: Rearwash, Ladywash and Comfortwash functions.
• Comfort: Heated seat, dryer, nightlight and powered lid functions.
• Installation: External water/electrical connections and model-specific bowl fit.

Duravit’s product information for article number 610000001040100 lists remote control, self-cleaning shower nozzle operation, seat heating, warm-air drying, two programmable user profiles, a nightlight, and button-actuated lid and seat functions.

Compatibility is the central limitation. Duravit identifies this SensoWash Starck version for Starck 2, Starck 3, and Darling New applications. It should not be treated as a universal elongated bidet seat.

Duravit now describes SensoWash Classic as the successor to SensoWash Starck. That makes current service support and exact replacement-part needs important checks before committing to the older platform.

Ease Of Use

Maintenance

Clean the seat and cleansing hardware only with products permitted by Duravit. Keep the external water and electrical connections accessible, and confirm current parts or technical support before servicing the motorized lid, seat, dryer, or wash system.

Kohler Innate vs Woodbridge B0960S: Is the Upgrade Worth It?

Both verified models replace the complete toilet and add bidet cleansing, heated seating, drying, remote operation, and automatic functions. The main trade-off is how much you value the Kohler’s additional cleansing, installation, and dual-flush features.

• Flush configuration: Kohler provides dual-flush control; Woodbridge uses a single-flush configuration.
• Wand care: Kohler specifies UV-light cleaning of the stainless-steel wand.
• Installation system: Kohler includes its ReadyLock system for a standard 12-inch rough-in.
• Warranty: Kohler specifies a three-year limited warranty; Woodbridge lists one year.

Which Smart Toilet or Bidet Seat Should You Buy?

• Want the most complete verified feature set: get the Kohler Innate.
• Want the lower-priced complete smart toilet: get the Woodbridge B0960S.
• Want dual-flush control and UV wand cleaning: get the Kohler Innate.
• Want chair-height seating with broad hands-free automation: get the Woodbridge B0960S.

How We Chose

• Current product status: We checked the linked Amazon listings and current manufacturer catalogs before recommending a model.
• Cleansing and comfort: We compared wash modes, temperature control, heated seating, drying, deodorization, and nozzle-care features.
• Installation: We checked rough-in requirements, bowl compatibility, water connections, power requirements, and full-fixture versus seat-only installation.
• Serviceability: We considered current manufacturer support, warranty information where available, and whether a model had been discontinued or superseded.
• Safety: Product-status and recall searches were included in the verification process. No hands-on performance testing is claimed.

Maintenance and Service

Smart bathroom fixtures combine plumbing with powered components, so maintenance involves more than ordinary bowl cleaning. Always follow the exact manual for approved cleaners, nozzle care, filter service, and electrical precautions.

• Keep connections accessible: Do not block the water shutoff, power connection, filters, or service points.
• Avoid harsh cleaners: Use only products allowed for the seat, nozzle, plastics, seals, and porcelain.
• Watch for leaks: Recheck new water connections after installation and investigate moisture promptly.
• Use qualified service when needed: Electrical, valve, motor, or internal flushing faults may require professional repair.

Smart Toilets and Bidet Seats Buying Guide

Complete Smart Toilet vs Bidet Seat

A complete smart toilet replaces the entire fixture and can integrate automatic flushing, lid movement, cleansing, heating, and drying. A bidet seat keeps the existing bowl, but fit must be exact. In this roundup, the two currently verified recommendations are complete toilets: the Kohler Innate and Woodbridge B0960S.

Rough-In, Bowl Shape and Physical Fit

For a complete toilet, measure from the finished wall to the center of the floor drain and compare that measurement with the manufacturer’s rough-in requirement. Both verified complete toilets here specify a standard 12-inch rough-in. For a seat, check the exact bowl series, bolt pattern, tank clearance, shape, and mounting requirements rather than relying on appearance alone.

Electrical Access

Electric bidets need a suitable power source near the toilet. Follow the product manual and local electrical requirements rather than using an improvised extension lead. The Kohler Innate specifically calls for a dedicated 120 V, 15 A, 60 Hz GFCI-protected circuit, so electrical planning should happen before the fixture arrives.

Water Supply and Shutoff Access

Confirm the supply connection, shutoff-valve location, and clearance required by the installation manual. Skirted one-piece toilets can hide more hardware than a conventional toilet, so an existing supply valve that works with your old fixture may not sit in the right place for a new smart model.

Cleansing and Comfort Features

Prioritize the controls you will actually use. Adjustable water temperature and pressure matter more for daily cleansing than a long list of rarely used extras. Heated seating and warm-air drying add comfort, while automatic lids and flushing reduce touch points. The Kohler Innate offers the broader verified feature set here.

Parts, Warranty and Long-Term Service

Electronic toilet components are more specialized than a basic fill valve or flapper. Check the manufacturer’s parts network, warranty, support contact, and model status before buying. This matters especially with older bidet seats: both seat-only products in the original comparison now have current-status concerns that keep them out of the recommended picks.

Mistakes to Avoid When Buying Smart Toilets and Bidet Seats

• Assuming every elongated seat fits: Match the exact mounting dimensions and manufacturer compatibility list.
• Ignoring the outlet: Confirm electrical requirements before removing the old toilet or seat.
• Checking only the rough-in: Also verify supply-valve location, side clearance, fixture dimensions, and service access.
• Buying a legacy model without checking support: Confirm current parts, warranty, and replacement options first.
• Using unapproved cleaners: Follow the manual so chemicals do not damage plastics, seals, nozzles, or coatings.

FAQs

Do Smart Toilets Need Special Installation?

Usually, yes. A complete smart toilet needs the correct drain rough-in, water-supply position, floor space, and electrical service specified by its manufacturer. Some models also use concealed mounting hardware. Check the installation sheet before ordering, and use qualified plumbing or electrical help whenever the work falls outside normal fixture replacement.

How Do I Know Whether a Bidet Seat Will Fit?

Start with the manufacturer’s compatibility information, not just whether the bowl looks round or elongated. Check mounting-hole spacing, bowl length, tank clearance, water connections, and any model-specific requirements. Some premium shower-toilet seats are designed around particular toilet families and are not universal retrofit products.

Will a Smart Toilet Work During a Power Outage?

Most powered comfort functions will stop when electricity is unavailable. That normally includes heated water, the heated seat, drying, deodorization, and motorized lid functions. Flushing during an outage varies by model, so check the manual for a mechanical, battery-backed, or emergency flushing method before buying if outages are a concern.

What Maintenance Should I Expect?

Expect normal bowl and exterior cleaning plus model-specific nozzle, filter, seal, and remote maintenance. Keep the water shutoff and electrical connection accessible, and avoid abrasive or chemically aggressive cleaners unless the manufacturer allows them. Electronic, motorized, or valve problems may require authorized parts or qualified service.

Should I Choose a Complete Smart Toilet or a Bidet Seat?

Choose a complete smart toilet when you want the most integrated appearance and features such as automatic flushing or concealed hardware. Choose a bidet seat when your existing toilet is in good condition and a current seat is confirmed to fit it. Seat compatibility should always be verified before purchase.

Do Smart Toilets Need a GFCI Outlet?

Follow the electrical specification for the exact model and your local code. Bathroom fixtures commonly have specific grounding and fault-protection requirements. The Kohler Innate in this guide specifically requires a dedicated 120 V, 15 A, 60 Hz GFCI-protected circuit. Other smart toilets and bidet seats may specify different electrical arrangements.

Final Verdict

For the smart toilets and bidet seats checked in September 2026, only two of the four original products remain strong current recommendations. Both are complete smart toilets, so shoppers who specifically want a seat-only upgrade should compare newer current seats rather than defaulting to either legacy model in this article.

For the Best value option, compare the Woodbridge B0960S; for the premium pick, the Kohler Innate remains the stronger verified choice.
